Looks great on Blu-ray, and has a fantastic ‘re watch’ factor. The series really picks up in season 2, the last half ramps up the action to a MASSIVE conclusion. You can dive into season 2– But I would recommend watching 1 first, as characterisation is beautifully constructed and flows from episode to episode. They'll annoy you, make you laugh, have you morally torn, the whole spectrum! Enjoy in the dark…
